NOTICE
Turbopump destruction due to gases with too high molecular masses
The pumping of gases with impermissible high molecular masses leads to the destruction of the tur-
bopump.
► Make sure that the gas mode is set correctly by
[P:027]
in the electronic drive unit.
► Consult Pfeiffer Vacuum before you use gases with higher molecular masses (> 80).
Commissioning the turbo pumping station
1. Make sure that the transport lock has been released.
2. Where applicable, ensure cooling water supply and flow rate.
3. Where applicable, ensure sealing gas supply and flow rate.
4. Provide the current supply for the product.
6.2 Switching on the turbo pumping station
Switching on the current supply
► Switch off the power supply at the main switch.
After being switched on, the DCU runs a self-test and a check of the connected instruments. The dura-
tion of the self-test is approx. 20 seconds and is visualized on the display with a progress bar.
Putting the pumping station into operation
►
Switch on the turbo pumping station.
6.3 Normal operation
Operating the DCU
► When working with the DCU 002 Pfeiffer Vacuum display and control unit, please see the associ-
ated operating instructions supplied in the shipment.

6.4 Operation with gas ballast (applies to MVP 015-2 only)
Steam or moisture from pumped media condensing in the backing pump will impact throughput. Inject-
ing gas ballast improves (reduces) condensate quantity. The pumping station reaches the specified final
vacuum more quickly.
